Application filed October 29,1901, SerialNo. 80,408. (Ndmodel-l To all whom it may concern:

Be it known that we, FREDERIOK KAMPFE, RICHARD KAMP'FE, and OTTO KAMPFE, citizens of the United 'States, residing in New York, borough of Brooklyn, and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

The object of this invention is to improve the safety-razor for which Letters Patent were granted to us, No. 672,984, on April 30, 1901, in such a mannerthat the blade-holding case can be conveniently opened at the rear part for permitting the cleaning of the case, the blade adjusted in a more accurate manner by means of retaining-clips and set-screws, the blade locked in position by means of a pivoted and spring-actuated. double clasp, and the guard device at the front part of the bladeholding case adjusted on its axis so as to permit the adjustment of the guard-fingers relatively to the edge of the blade; and for this purpose the invention consists in the construction of the blade-holding case, an improved device for adjusting the blade on the case, a double spring-actuated clasp for looking the blade to the casing, and a rotatable guard device pivoted at the front part of the.

casing so as to be adjustable relatively to the edge of the blade, as will be fully described hereinafter and claims.

In the accompanying drawings, Figure 1 represents a front view of our improved safetyrazor. Fig. 2 is aside elevation of the same. Fig. 3 is a top view showing the upper top part of the blade-holding case shifted longitudinally on the lower portion for permitting the opening of the same. Fig. 4 is a vertical detail section of v.the mechanism for ad-.

j usting the blade on the blade-holding case. Figs. 5 and 6 are respectively a front and a side elevation of a safety-razor, showing the improved double clasp for holding the back of the blade and the axially-adj ustable guard device. Fig. 7 is a rear elevation of the safety-razor shownin Fig. 5. Fig. 8 is a vertioal transverse section on line 8 8, Fig. 5. Fig. 9 is a vertical section through the guard device on line!) 9, Fig. 8; and Fig. 10 is a definally pointed out in the tail perspective view of the improved double clasp forlooking the blade to the casing.

Similar-letters of referenceindicate corresponding parts.

Referring to'the drawings, B represents th lower, and C the upper, part of the blade-holding casing, which is preferablymade of metal and substantially U-shaped in cross-section. The angular upper part 0 is hinged to the upper edge of the lower part in such manner that said top part can be swung in upward and backward directions, so as to fully eX- pose the underside of the top part C and the upperside of the lower part B. When the top part (lie in its usual position over the lower partB, the rear portion of the top part O forms the rear wall of the casing in continuation of the rear portion of the bottom part B. The upper edge of the lower part B and the lower edge of the upper part 0 are recessed at adjacent points, sofas to permit the shifting of the top part 0 in longitudinal directions on pintles of the lower part, as shown in Fig. 3. The pintles d are attached to ears d at the upper edge of the lower part B,so that the ears d? of the upper part can beshifted on the pintles from the position shown in Fig. 1 to that shown in Fig. 3 and back again to the normal position shown in Fig. 1. part B is provided at its upper-edge with an inwardly and upwardly projectinghook 61 which interlocks with an inwardly-projectin g lug d at the lower edge of the upper part 0 when the parts are in normal position, while the hook d andlug: dfeleareach; other when the upper'partfi is shifted longitudinally on the lower part, so that the former can swing in upward and backward directions in position as shown in dotted lines in Fig. 8. For returning the upper" part into its normallylocked position it is moved in forward direction again and then shifted longitudinally on the pintles. The ears d of the upper part are slidback on the pintles, and the inwardly The lowerprojecting lug d is reengaged by the hook d theupper part, as shown in Figs. 1 to 3. In place ofthe springs a two coil-springs 6' may be used, which are placed on the pintles d d and the opposite ends of which engage the lower and upper parts B and C of the casing, as shown in Figs. 5 to 7. The springs e or 6 move the upper part of the casing in backward direction as soon as the same is shifted on the pintlcs so that the lug d clears the hook 61 The upper portion of the top part 0 is slightly concaved and provided with openings and at each end with a straight and slotted end piece F, which serves to guide the blade in the conventional manner. At each end of the top part C is arranged on the slotted portion of each end piece F a retaining-clip G of any approved construction. The shanks of the retaining-clips are guided in the slots of the end pieces F by slide-pieces g and firmly clamped to the end pieces by screws g, which engage the slide-pieces g and the heads of which are adapted to be engaged by a suitable key. The clips G bind by their inclined forwardlyextending ends on the ends of the blade, so as to hold it firmly in position on the concaved portion of the top part 0. As the size of the blades used varies within certain limits it is-of considerable advantage to adjust the clips G accurately on the ends of the blades either in forward or backward direction. This is accomplished by means of set-screws 9 which pass through the upper part of the casing, near the angular bend of the same, said set-screws having collars, so as to turn freely in holes of the casing,while their inner ends engage inwardly-bent lugs at the rear ends of the slide-pieces g. The outer ends of the set-screws g are provided with heads adapted to be engaged by the same key by which the clamping-screws g are adjusted. By the set-screws g and clamping-screws g the clips G are readily adjusted to the required position on the blade as required by the size of the same. By this adjustment of the clips G in forward or backward direction as required by the blade the clamping-screws g require only to be loosened sufficiently for permitting the adjustment of the set-screws 9 after which the screws 9 and clips G are clamped firmly in position. By this arrangement of clampingscrews and set-screws there is no danger of disconnection of the clips G from the slotted end pieces F and consequent loss of the same.

The blade is retained in position by the ordinary blade-retaining spring H which is pivoted to the rear of the top part 0 and adapted to be swung up so as to bear upon the back of the blade and hold it in position in the clips G. In place of the spring H, a double spring-clasp II may be used, which is hinged at the angle of the top part C, said top part being recessed as shown in Fig. 7, and pintles h formed in the top part 0. The double spring-clasp II is hinged to said pi ntles and provided with two bent-up lugs h at its upper end, and an upwardly-bent central portion or handle-piece 71, by which the springclasp is moved forward and backward, so that its side lugs it either engage or release the back of the blade. Below the central .portion 7L2 is arranged at the lower end of the clasp H a forwardly-bent heel it that is engaged by a flat spring h", the forward end of which is riveted to the under side of the concaved portion of the top part 0, as shown in Fig. 8, so as to hold the blade-retaining i .the rear part i, that is provided with inwardlybent ears 2' at the ends, which are pivoted to stationary ears 2'" at the front ends of the end pieces F and engaged by screwsi'f, having rectangular heads. The screws t" form the pivots of the rotary guard device D, so that the samemay be turned and then set at different relative positions toward the edge of the blade. The screws engage nuts i at the inner sides of the ears i said nuts having each a finger i, adapted to abut against the back 2', and thereby prevent turning of the nuts, said fingers projecting into the path of the blade and forming a stop for the same, as shown in Fig. 6. When hair-stubble of considerable length is to be shaved, the rotary guard device has to be set forward to a greater extent than when shorter stubble is to be shaved, so as to bring the hair to a greater or less extent in the space between the teeth and permit the effective action of the edge of the blade thereon. The adjustment of the set-screws i" may be performed by the same key by which the adjustment of the clamping-screws and set-screws of the clips G is produced. The rotary guard device D, with curved or are-shaped teeth, permits the adjustment of the guard to the growth of the hair, gives a better hold on the stubble according to its length, and permits easier and quicker shaving.

The advantages of our improved safetyrazor 'are, first, that the blade-holding casing can be quickly and conveniently opened for the purpose of cleaning the dilferent parts; secondly, that the blade can be locked in a Very convenient manner by the double spring-clasp; thirdly, that the blade can be adjusted. easily and accurately relatively to the teeth of the guard device, and, lastly, that the guard device can be readily turned on its axis and adjusted for the longer or shorter growth of hair to be shaved.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a safety-razor, the combination, with a blade-holding casing consisting of a lower part and a top part hinged thereto, of a looking device for holding the top part in normally closed position on the lower part, and
